Food chain and Food Web ,definition, diagram and examples

Food chain and Food Web ,definition, diagram and examples and Food Chain and Food Web, Food Chain and Food Web- food chain is a series of interlinked organism for food taking from one another and Food Web is interconnected food chain that make web like structure. Food chain is necessary for ecological balance in nature in which no one species can found in nature but all the species are found in balance way by eating one another.

food chain definition in biology

food chain is a series of groups of different organisms called trophic level in which there is repeated eating and eaten by so as to transmit the food energy is known as food chain and trophic level acts as food link in a food chain.

What are characteristics of food chain

1) in food chain there is repeated eating process in which food is eaten by smaller one and one and that is eaten by larger one so the food chain involves nutritive interaction between biotic component of ecosystem.

2) plants and animals which depend one another form the limbs of a food chain

3) in food chain there is a unidirectional flow of energy from sun to producer and than to series of primary consumer secondary consumer tertiary consumer and quaternary consumer of various steps.

4) usually about 80 to 90% of potential energy is lost because of heat transfer on the basis of second law of thermodynamics

5) usualy food chains have four or five trophic level shorter food chain will provide greater available energy

6) food chain is always straight

7) omnivorous animals in food chain generally occupy more than one trophic Level

8) the food chain start with producer community and end with consumer community

What is definition of trophic level in food chain

all the steps in food chain is known as trophic level. In food chain first trophic level is producer community ,second trophic level is primary consumer community that is herbivorous animals and Third trophic Level is secondary consumer community which is carnivorous animals and also 4th and 5th trophic level is tertiary and quaternary consumer community which is carnivorous animals in nature.

What are different types of food chains

in natural environment there is two types of food chain:-

1) grazing food chain ( GFC)
2) Detritus food chain ( DFC)

What is grazing food chain

 these are directly dependent upon solar radiation is the primary source of energy and green plant or producer form the first trophic levels of food chain and herbivorous or primary consumer eat upon the producer community form the second trophic level and each of primary consumer community is eaten by carnivorous animals which form the third trophic Level and a small carnivorous animals eaten by large carnivorous animal which form fourth and fifth trophic level in food chain.

What is Detritus food chain

in this types of food chain primary source of energy is detritus dead organic matter, all dead parts of plants and animals is eaten by microorganism like protozoans bacteria and fungi. This food chain is shorter than grazing food chain.

What are examples of grazing food chain

1) in grassland ecosystem

A) grass — insects—frogs—snakes–eagle

B) grass—rats—snake—birds—lion

C) grass—rabbit—fox—wolf–lion

Food chain in pond ecosystem

2) in pond ecosystem

A) phytoplankton —-zooplanktons —small fish —–large fish —-predatory Birds

3) in forest ecosystem

A) tree— herbivore animals— birds —tiger

Food chain in forest ecosystem

What are examples of detritus food chains

Fallen leaves and dead body— fungi, bacteria
—-Insect larva,mollusca– small fish —-large fish.

What is food web definition

it is a network of food chain which become interconnected at various trophic level to make web like structure.

What is characteristics of food web

in ecosystem no food chain is independent and linear arrangement but it is formed by interlinking of three types of food chains predatory food chains ,parasitic food chains and saprophytic food chains.

The food web provides the alternative pathway of food availability and also checking the overpopulation of species.

Food web examples:- A food web is the natural interconnection of food chains and a graphical representation of what-eats-what in an ecological community. It is basically a relationship between ecological community. Interconnection of food chain found in terrestrial and aquatic habitat.

Terrestrial food web:– in terrestrial habitat, primary producer is green grasses and plants, it produce food for primary consumer like grasshopper, rabbit and Mouse, all three primary consumer which are herbivorous produce food for secondary consumer like a snake, lizard and Hawk.

This is very easy and simple food web diagram important for class 3, 4, 5, 6, 7, 8, 9, 10, 11 and 12 students. Food web diagram in terrestrial and pond ecosystem.
